[Flashcoders] Flex sdk set up question

[Dave Segal]

Sorry to ask a Flex question here but I'm sure one of you knows the answer
or at least can point me to the place I can find the answer.

I am using Flex builder to build a pure AS project. I have been using the
3.0 sdk without a problem. When I updated the SDK to in order to build a
Flash 10 project the compiler can't find the core flash package. So base
stuff like "MovieClip" does not exist. I pretty much just downloaded the
SDK and added via the preferences dialogue. I've tried the 3.2, 3.3, 4.0
SDKs with the same results. I'm sure I am missing some step but I'm not
sure what.

Also, where is the best forum for asking Flex questions?

Thanks

[Flashcoders] Document class constructor

[Dave Segal]

What is the order of execution for the document class constructor. The
behavior seems inconsistent. For example, when I load my swf independently
calling this.loaderInfo.url in the constructor returns the correct url.
However, the same thing returns null if my swf is loaded by another swf. 

 

Is it safe to do this or will it create a race condition when the swf is
loaded independently?

 

public function DocumentClassConstructor()

{

  trace(this.loaderInfo.url); // url might be null

this.loaderInfo.addEventListener(Event.COMPLETE, init);

}

 

public function init()

{

  // everything is ready, proceed

trace(this.loaderInfo.url); // always return the url

}

Re: [Flashcoders] id3 runtime error

[Dave Segal]

I see the request in the headers and when I debug with Flex, the variables all 
appear to be declared correctly. I tried hardcoding the url as well but I get 
the same issue. I'm stumped. I suppose I can just catch the error and try to 
reload the mp3 file though that is a very unsatisfying solution.

I'll see if I can create a simple example of the issue and post to the forum.

Thanks for you helping Taka.

Do you have firebug?

Is it possible that it's using the wrong path or even trying to
request "" when it makes the call? If you have firebug, you can look
at all of the http requests through the net panel.

If you're using a variable to make the load call, try hardcoding a
value and see if that solves the issue...

Although, I'm not sure if Flash is throwing the security error if it
will even show up.

Can you paste the code that does the loading and event handling?

Joel,
I am not sure of the ID3 version. Does that matter? Would different versions of 
the ID3 tags cause this type of inconsistent failure?

This is the error I am seeing. Strangely the part after the word "access" is 
left blank. Which leads me to believe it is some kind of timing bug on my side 
however, the trigger for this function is the ID3 event. I also tried waiting 
for the COMPLETE event but the same issue occurs. As I mentioned the mp3 file 
is on the same server so I'm not sure why it would be looking for a policy file 
at all. The files are in different directories however if that gives some clue.

I have a bug that is driving me nuts. I am loading an mp3 file from the
same server as my swf. About 1 in 30 tries when trying to reading the id3
tags after the ID3 event I get a runtime error telling me I need to load

RE: [Flashcoders] Flash 10 file upload

[Dave Segal]

Actually this is not the way security updates were made in the past. With
other updates, for instance the introduction of and multiple changes to
the "allowDomain" rules, backward compatibility was maintained for older
versions.

I agree with Juan, breaking a feature that has been supported for years is
a serious lack of respect for users of the platform. I guess it's time to
start looking at the alternatives to Flash that are out there.

The problem is if they took that approach, the vague security hole would
continue to exist - a potential exploit would simply need to compile for
an
old version of the player.

It's awful, but I wouldn't really say it's an "stupid" decision. As soon
as
they decided to cripple the functionality, making it global is the only
way
to go. It's a no-win situation. This is also the way certain similar
security decisions have been made in the past.

I think the only real solution would be to let it work as usual, BUT add
an
optional checkbox to the file browsing dialog that would let the user
disable further dialogs from that Flash movie (or at least THEN make it
respond to events only), in the same vein Google Chrome does with
Javascript
dialog popups. It works very well to combat the focus-stealing exploits,
and
I'm not sure why Adobe didn't take that route instead.

RE: [Flashcoders] Flash 10 file upload

[Dave Segal]

The file upload has to occur as the result of a user interaction. If you
are doing any upload that is not associated with button click Flash 10
rejects the upload. The change is not backward compatible. Flash 8 and 9
content that do not conform is broken.

Here are couple articles on the topic and the F10 security documentation.

[Flashcoders] GC-ing a SharedObject

[Dave Segal]

I have a large scale project I am working on that needs to be loaded and
unload so of course I am running into the dreaded AS3 garbage collection
mess.

I've tracked down the problem to a local SharedObject of a particular
class. The destructor of said class closes the SharedObject (even though
that shouldn't be necessary since it is local) and nulls the variable but
it seems this is not enough for the garbage collector. The memory is not
released. However, if I never create the SharedObject in the first place
and go through the same destruction procedure memory is released!

Help!

Thanks for the response Erik.

Yes, I am aware that compiling the entire base class of another swf is

Anyway, I am very interested in seeing your example files, whether in Flex

[Flashcoders] as3 namespace question

[Dave Segal]

I posted about this before and didn't receive and answer but it is still
causing me issues so I am trying again. I need to load an swf from one
server that is a member of some class. For example:

 

http://server1.mydomain.com/load_me.swf that uses the Document class
"com.mydomain.componet.LoadMe.as".

 

I want to be able to load this swf from a different server, say
http://server2.mydomain.com/load_stuff.swf, and cast it to a LoadMe when
it is done loading. Should this work? I keep getting errors when trying to
cast in the init handler.

 

 

import com.mydomain.componet.LoadMe;

 

var _req:URLRequest = new
URLRequest("http://server1.mydomain.com/load_me.swf";);

var _ldr:Loader = new Loader();

var _context:LoaderContext = new LoaderContext();

_context.securityDomain = SecurityDomain.currentDomain;

_context.applicationDomain = ApplicationDomain.currentDomain;

_ldr.contentLoaderInfo.addEventListener(Event.INIT, initHandler, false, 0,
true);

_ldr.load(_req, _context); 

 

 

private function initHandler($event:Event) () {   

var _lm:LoadMe = LoadMe(_ldr.content);

}

[Flashcoders] to mac or not to mac

[Dave Segal]

It's time for me to get a new computer and I have heard so many horror
stories about Vista that I am thinking of switching to Mac. What tools are
people using to develop on the Mac. I mostly Flash IDE, FlexBuilder,
FlashDevelop, SWFMill, SWFDump, HaXe, FlashTracer - are these available on
Mac? Also any general info about developing on the Mac, positive or
negative, would be helpful. 

Is anyone using Vista and enjoying it?

RE: [Flashcoders] LoaderContext question

[Dave Segal]

I am getting a type Coercion error. "TypeError: Error #1034: Type Coercion
failed"

Really the whole goal here is to be able to load swfs (from a different
server) that implement some public api. Then have the loading swf cast the
loaded swf to that api, so code hints and type checking are available. Are
there any solutions for this type of thing?

[Flashcoders] LoaderContext question

[Dave Segal]

I need to load an swf from one server that is a member of some class. For
example:

 

http://server1.mydomain.com/load_me.swf that uses the Document class
"com.mydomain.componet.LoadMe.as".

 

I want to be able to load this swf from different server, say
http://server2.mydomain.com/load_stuff.swf, and cast it to a LoadMe when
it is done loading. Should this work? I keep getting errors when trying to
cast in the init handler.

 

 

import com.mydomain.componet.LoadMe;

 

var _req:URLRequest = new
URLRequest("http://server1.mydomain.com/load_me.swf";);

var _ldr:Loader = new Loader();

var _context:LoaderContext = new LoaderContext();

_context.securityDomain = SecurityDomain.currentDomain;

_context.applicationDomain = ApplicationDomain.currentDomain;

_ldr.contentLoaderInfo.addEventListener(Event.INIT, initHandler, false, 0,
true);

_ldr.load(_req, _context); 

 

 

private function initHandler($event:Event) () {   

var _lm:LoadMe = LoadMe(_ldr.content);

}

[Flashcoders] frame rate guidelines

[Dave Segal]

Are there any general guidelines about what frame rate to use when
publishing an swf?

 

Also, are there any techniques for adjusting the frame rate of an swf at
runtime?

[Flashcoders] AVM1 loadMovie problems

[Dave Segal]

I am  having some problems loading multiple Flash 8 movies into Flash 9. I
understand that this not recommended and that is preferred to work with
all Flash 9/AS 3 content. 

 

Here is the situation. I have 2 Flash 8 swfs, let's call these
"f8loader1.swf" and "f8loader2.swf". Both of these swfs instantiate the
same class, "F8AssestClass",  which loads another Flash 8 swf,
"f8asset.swf".   In my Flash 9 application I am loading "f8loader1.swf"
which instantiates "F8AssetClass" which loads "f8asset.swf" just as
planned.  However, when I then load "f8loader2.swf", it starts up and
instantiates "F8AssetClass" but "f8asset.swf" never loads. I have tried to
load "f8asset.swf" with both loadMovie and with the MovieClipLoader. It
never loads the second time.

 

I have a project where the above scenario is going to be in play multiple
times and I don't have much flexibility to adjust the Flash 8 content. I'm
hoping someone can help me understand what is happening here and let me
know if whether it is possible to achieve this. 

 

I have example files I can send if anyone is interested.

[Flashcoders] System.as vs System.security

[Dave Segal]

I asked a question about this on Friday with no response but here goes
again this time with more details. It seems like the Flash compiler is
choking on the System class when I delete the ASO cache and compile. Here
is all the code in my test fla:

System.security.allowDomain(" 
www.mydomain.com");
System.exactSettings = false;
 
and here is the compiler error I get from the System.as:
 
**Error** C:\Documents and Settings\dave\Local Settings\Application
Data\Macromedia\Flash 8\en\Configuration\Classes\FP8\System.as: Line 7:
The name of this class, 'System', conflicts with the name of another class
that was loaded.
 {
 
 
Switch the order of the lines:
System.exactSettings = false;
System.security.allowDomain(" 
www.mydomain.com");
 
and here is the compiler error I get from the security.as class
 
**Error** C:\Documents and Settings\dave\Local Settings\Application
Data\Macromedia\Flash 8\en\Configuration\Classes\FP8\System\security.as:
Line 7: The name of this class, 'System.security', conflicts with the name
of another class that was loaded, 'System'.
 
 
It seems that the problem is related to the fact that there is both a
System.as class, which defines exactSettings, useCodepage,  setClipboard,
etc, and a System folder which contains the System.security,
System.capabilities, and System.IME classes. When both the System package
and the System class are referenced the compiler throws an error. I
searched around and was surprised that I couldn't find any information
related to the conflict. Does anyone know how to resolve this?
Thanks
Dave

[Flashcoders] compiler error from System class

[Dave Segal]

Someone on my team keeps getting compiler errors like this.

**Error** C:\Documents and Settings\Smyer\Local Settings\Application
Data\Macromedia\Flash 8\en\Configuration\Classes\FP8\System\security.as: 

Line 7: The name of this class, 'System.security', conflicts with the name
of another class that was loaded, 'System'.

The error only occurs when the ASO cache is deleted. On subsequent
compilation without deleting the ASO cache the file compiles fine. Anyone
have any insight into why this would be happening?

RE: [Flashcoders] Detecting embedded domain?

[Dave Segal]

Someone else on this list hooked me up with this a while back. It works as 
long as JavaScript is not restricted on the pages your swf is embedded on 
(see mySpace).

var embedded_domain:String = flash.external.ExternalInterface.call("eval", 
"location.href");

Building a video player that can be embedded in a web page. We'd like to be 
able to detect what domain the page the player is embedded on lives.
If the domain is not ours (eg, SI.com), we'd like to display a logo; if it 
is ours, we don't want to display the logo.



Does anyone know how to detect what the domain is for a page that the SWF is 
embedded on?

[Flashcoders] Security error "tried to access incompatible context"

[Dave Segal]

I have local file that is loading a remote file. The remote file sends a
number of events to the file that loads it. I have
System.security.allowDomain in the loading file set to allow the domain of
the file that is loaded. Events are received, everything works, no
problem.
 
But, I keep getting errors in the Flash IDE output window that say "tried
to access incompatible context". 
 
Like this :
 
*** Security Sandbox Violation ***
SecurityDomain 'http://my.domain.com/my_swf.swf' tried to access
incompatible context 'file:///C|/my_local.swf'
 
I read that this is the expected behavior for the debug version of the
flash player. But it is quite annoying. Is there a way to suppress it? 
Thanks

[Flashcoders] RE: swf and referring domain

[Dave Segal]

Thanks for the response Joey. I actually tried a similar method before that
almost worked. From Flash I did this - 

getURL("javascript:document.mySWF.SetVariable('referringDomain',document.loc
ation.host)"); 

The problem I ran into was that in IE as soon as this line executes the page
stops rendering. This is especially problematic when the swf begins before
the page is done loading. The page never completes. Also, several sites I am
targeting, like mySpace, restrict javascript. I'm not sure what would happen
if I tried writing javascript at runtime to a mySpace page.

[Flashcoders] Re: swf and referring domain

[Dave Segal]

Thanks for the response Ray but that is not really what I am looking for. I
don't want to prevent others from using my swf. I just want an way to
identify the referring domain when it is embedded. Specifically, I want
people to embed my swf from my server on their web pages (hosted by myspace
or anywhere else) and have the player detect at runtime where the request is
coming from. Unfortunately using php or asp for referrer detection is not an
option. I am hoping there is a way to get it from the player. I figure the
player must know about the referring domain as it is able to block or accept
calls from the page with the allowscriptaccess parameter.

[Flashcoders] swf and referring domain

Is there a way to find the domain of the page that loads my swf. For
example, someone embeds an swf served from my server on their
www.myspace.com   page. Is there is way for me to
determine that the request is coming from myspace.com at runtime?
